Members of the Quincy Police Department, the Adams County Sheriff's Department and U.S. Marshal's Fugitive Task Force were involved in Carter's arrest.

On Friday morning, less than three hours before Carter was taken into custody, Adams County State's Attorney Jon Barnard issued a warrant for Carter's arrest.

Carter is charged with first-degree murder. Bond is set at $1 million. He is being lodged in the Adams County Jail. Barnard said Carter will make his first court appearance Monday morning.

After his arrest, Carter spent six hours at the Quincy Police Department headquarters. He was interrogated for most of that time. He was transferred to the Adams County Jail just as dusk set about 5 p.m. He wore a black parka with its hood up, trying his best to shield his face from the media gathered to get his photo as he made a short walk from an unmarked police car into the Adams County Courthouse.

Summers said Carter is originally from the Chicago area, but has been living in Quincy. Carter was living with another person at the place of the shooting. Summers said Carter has a previous criminal history, but not in Adams County.

Williams, the man killed in the shooting, was remembered as a "super nice guy" by Gary Fuller, who said he knew Williams for three years. Williams lived in the Indian Hills housing complex on Quincy's southwest side.

"He helped everyone out around here," Fuller said Friday morning as he spread salt on icy sidewalks at the complex.

Fuller said Williams was unemployed and lived with his girlfriend.

At the site of the shooting, a note from the postal service was stuck to the door. Carter lived in Apartment 1 at the building on South 11th.

The scene Friday was quiet, a far cry from Thursday afternoon, when police ringed the building in yellow caution tape as they started the search for Carter.

Seth Hickey lives in Apartment 3, on the ground level next to where Carter lived and where the shooting took place.

"I got out of the shower and kind of heard some loud talking," Hickey said. "It wasn't quite yelling, but it was close to it."

Hickey, 20, originally of Phoenix, works on the third shift at a local manufacturer. He said he slept through the shooting. He said a Quincy officer woke him.

"I locked my door and stayed in after that," said Hickey, who has lived at the complex for two years.

Hickey said he didn't know Carter other than seeing him in passing.

"I brushed into him every now and then," he said.

Hickey said the building has a bad reputation.

"There are a lot of drugs here, I guess," he said.

No one else in the building of six apartments was injured.

The Adams County Geographic Information System website lists Ganad Trust as the owner of the building. Neil Klingenberg is listed as trustee.
